The RPI GTS exhaust system for the BMW E60 M5 offers the same aggressive race car sound and performance as our popular GT system but is about 15-20% quieter. Made of high quality T-304 stainless steel, our GT system shares the same design as our ST street system with the exception of no catalytic convertor. Expect a 10-17whp gain and a weight saving of over 50lbs from the stock system (stock:122lbs vs. RPi: 62lbs).

Picture of the Straight Pipes

RPi's Straight Pipes replace the heavy stock front secondary cat pipes for better flow. These pipes are featherweight at just 4 lbs per pipe. Expect 5-8 WHP over the stock front pipe. Your stock headers have built-in cats, so your M5 will still have cats.
